Summary
A novel 3D surgical positioner aids in precise cartilage graft placement and sculpting for microtia reconstruction, improving auricular reconstruction outcomes.
Area of Science:
- Plastic Surgery
- Biomedical Engineering
- Medical Device Design
Background:
- Microtia reconstruction requires precise cartilage graft placement and sculpting.
- Existing methods may lack accuracy in positioning and shaping the graft.
Observation:
- A 3D surgical positioner was fabricated using a silicone mold of a wax prototype.
- The positioner utilizes the patient's auricular defect contour for stable intraoperative fixation.
Findings:
- The microtia surgical positioner accurately guided the superior-inferior, anterior-posterior, and rotational placement of the cartilage graft.
- The device facilitated detailed sculpting of the autogenous rib cartilage graft.
Implications:
- This collaborative approach between medical artists and surgeons enhances total auricular reconstruction.
- The surgical positioner offers a reproducible method for accurate graft positioning and shaping.
